Hello, Internet. Today is as good a day as any to be sad about things, so why not be sad about the death of both Yoda, 2011's world's ugliest dog, and an adorable mutant earless bunny? One of them died a peaceful death, at least, while the other one died a very quick, albeit ridiculously tragic death.

Mark Meyerhoff and his colleagues have made a discovery that could potentially revolutionize the treatment of diabetes: Tears can be used to track blood sugar levels. As I'm sure you are aware from those commercials involving B.B. King, for the moment, diabetics who need to check their blood sugar (as they frequently do) are stuck with the current, inconvenient solution of pricking their fingers and drawing literal blood to test. Granted, it's not always the fingers, but the fact remains that diabetics have to make themselves bleed on a daily basis just to get by. Meyerhoff is hoping this discovery will change that.
